Inheritance of gene expression in F1 hybrids of S. cerevisiae and S. paradoxus. (A) Hypothetical patterns of gene expression in S. paradoxus (red), S. cerevisiae (blue), and F1 hybrid yeast (purple), depicting six modes of gene expression inheritance. (B) Scatterplots showing the difference between mRNA expression levels (left) in the F1 hybrid and S. cerevisiae (x-axis) and S. paradoxus (y-axis). The difference between ribosome occupancy levels (RPF) in the F1 hybrid and parental species is shown on the right. Bar plots show the number of genes in each inheritance category from ribosome occupancy data. Genes with overdominant (overexpressed) and underdominant (underexpressed) inheritance occur much less frequently when considering ribosome occupancy, as compared to misexpression in mRNA abundance.
